First off, sorry if I posted this in the wrong category. I’ve never posted here before.
As far as I can tell, there’s no “official” word for what I’m trying to do. I’ll try to explain as best as I can:
What I’ve been trying to do is to quickly switch between textures on a character’s face to show different facial expressions. For example, the eyes and mouth might have “open” and “closed” textures to simulate blinking and talking.
For example, this model: (which is pretty close to what I want to do, but it only works in blender.)
… uses these texture atlas to show different emotions:
This can make a variety of facial features:
Some (bad?) solutions I’ve came up with are:
- Use a separate eye and mouth meshes that seamlessly transition with the head mesh, and switch the textures on that. However, I’ve read that splitting up a mesh unnecessarily is bad practice in JME.
- Replace the entire head/body texture with slightly different ones that each have the various combinations of eye and mouth states. But then I would be sending redundant texture data to the GPU repeatedly. (I think?)
Right now I’m using the first method, but I’d like to know if there’s a better way.
Any guidance on what I should do?
